*facepalm* Average Joes use GPGPU and CPU crunching on an everyday basis. In simple terms folding is a program optimized to take advantage of that power like you where just talking about in your previous post. You dont need to be an engineer or have a PHD or build super computers to see the exceptional difference in computing power between CPUs and GPUs. Only a fool would say a GPU isnt more powerful than a CPU when used in the same way. To be more specific, we wouldnt be slowly getting programs to encode ect on GPUs if CPUs could do it faster. Instead, its the other way around. People are screaming to do that processing on their GPUs just because they ARE so much faster. Numbers dont mean squat to me on a piece of paper, only evidence you can clearly see. Thats why i dont eat the hype over new GPUs or CPUs that arent even out yet. If my 4 core i5 can out fold a PS3, then my 465 can pretty much double even that...im gonna go out on a limb and say 6/8 core Xeons with HT paired with Tesla units will smash PS3s in computing power. On a 2 million dollar budget, thats alot of Xeons and Teslas no matter how much they cost individually. To put an argument aside before it arises, im using folding as an example of computing power, not in literal terms for a number to number argument.
Way old news? The article was posted 8 days ago....i dont call that old. The age of it is irrelevant though, considering the topic is on the computing power between A and B....not how old the topic is.
And "average" Joe doesn't have a clue how it works. It's like asking a frequent flyer about aerodynamics and jet engine design.
Also F@H is hardly the killer proof for your augment, last time I checked the point values are arbitrary so using them to compare performance is meaningless. Also if I'm not mistaken cpu's and gpu's don't even do the same types of work.
No offense but the Beckton + Tesla counterpoint isn't a good idea. For starters at best you just doubled you software development costs by throwing in two different architectures that are both going to require unique code. Although in the real world it is likely quite a bit more than double the cost because of the aforementioned difficulty of coding for gpu's. . Finally I don't think you realize just how much a Beckton server costs, a Dell Poweredge R910 with 2x 2ghz 8 core Xeons starts at ~$20,000. For that price you can get nearly 70 PS3's which will likely outperform it by a significant margin.
The last time an article was posted about PS3's I criticized them for not using GPGPU too but since then I learned just how uninformed I was about how HPC is really done. Needless to say approaching HPC from the perspective of PC gaming and overclocking doesn't work very well.
